i Mechanism 69 isefiective forreciprocating the slide 61 onthe guide 60 toward andfrom the table'67. This slide 61: is shown as'pro vided with flange 11 for engaging flange 13 of sleeve 14within outer sleeve 20. Within the sleeve-14 isshaft 25ha'ving diametricaI- ly disposed fixed roller projections 24coactfixed ear 71 with which coact nuts 72 adjust ably connecting to this slide 61 depending rod 73 having cam with abrupt portion 7 land arm 77 of angle-lever having fuleruml7 8 in base 7 9'of the frame 1.' This angle lever has additional arm 80 from which extends-link- 81to arm 82 fast on fulcrum 83. 1 From this fulcrum 88 depends arm 84- fixed with' the' arm82. r 'i y l y This arm '84carries roller 85 coacting with lowercam face 86 of lever having fulcrum 87 and upper thrust ball bearing or seat88 awshort arm distance from this fulcrum 87: This fulcrum 87 is in lever 89 having fixed fulcrum-90 andabout which the fulcrum 87 is rocked by opposing bolts 91. *This'l fixed fulcrum' 87 for thelever having cam face 86 is [thus'onewhi'ch maybeve'ry nicely'adjusted into its fixed position for holding the,

lever having the cam face 86 on the bearing 88. This ball bearing 88 is inposition at step or seat 92 of shaft 93 in bearing '94 of the frame base 7 9. This shaft 93 is the fixed bearing for the rotary tablef67'c'oaxial with the shaft 25.

:As the slide 61 is elevated rof therollers 24v to move toward entrance into the cam portions 22, the-cam 74 is effective on the roller 76 so to rock the angle lever 77, 80',- thatthe roller 85 may act on the cam face 86 for sufficiently lifting the shaft 93 and" the table 67 that the load of this table 67 and its carried parts arerelieved, if not actu-y ally clear-of, friction supporting bearing 95' ofthebase79, p q 1 Fixed with the arms 82, 84,is fork terminus arm 96 which, in this movementof the levers 'andlinlx'age,swings downward against, j

is also receiving frictional braking action in contacting with thebearing 95 .because the rolleri'85 has'so moved along thecam face I 86 f he st b r 88,:9 n s a tainingas much or any of, the load of this table67 andits:carriedp'artsr-flg ,7. There is accordingly [a frictional braking of the rotation step or indexing shifting of th t le'a h ca PQr Qns 22erqfiecr 1 l As this idle stroke in ,liftis completed, the

reverse travel of the slide 161'. occursgwhich is after the table, 67 hasibeen 'broug'htto the A stoppositionand the pin 98 has entered an opening 101 at the rest position of the table 67.
